// Reverse bits of a given 32 bits.
// The input must be a binary string of length 32
// Example : input: n = 00000010100101000001111010011100,
Output: 964176192 (00111001011110000010100101000000) - reversed.

// P.S onlinephp returns correct answer: 964176192, but
// leet code returns 1 at the same case,
// can someone explain to me in the comments ? by Luka Khitaridze
